Answer 1

Scam.

1) Proven not to work

2) If it did work, wouldn't it have a "gallons per pill" designation?

3) There is no three.

Answer 2

i dont think these work, my uncle tried these MPG pills and it says itll start to work after a few tanks of gas. its been at least 20 tanks of gas and the milage is still the same, and yeah they're all highway miles. its not mixed with city n highway.

Answer 3

save your money....none of these gimmick's were ever proven to work by any real professional testing other than the tests that the company trying to sell them to you says they passed....save your cash...don't buy them....think about it if these really worked they would be sold at every store,gas station,in the world ..u would be hearing about these on every news channel.......don't get fooled!
